ANEMIA, HEMATURIA, AND MULTICENTRIC URINARY NEOPLASIA IN A LLAMA (LAMA-GLAMA) EXPOSED TO BRACKEN FERN

An adult male llama (Lama glama) was euthanized because of severe chro nic hematuria and accompanying anemia. Pathology was limited to the ur inary system and consisted of multicentric bilateral transitional cell carcinoma of the renal calyces, ureteral transitional cell papilloma, and diffuse urothelial hyperplasia. This animal had been pastured for years in an area contaminated with the carcinogen-containing plant br acken fern (Pteridium aquilinum). The lesions in this animal resembled those seen in cattle consuming bracken fern, and it appears that llam as may be susceptible to the urinary carcinogenic effects of bracken f ern.
